GOAT (#16) is a peer-to-peer marketplace for buying and selling authenticated streetwear and sneakers.

Founded in 2013 as a late-night service for college students to order junk food, rolling papers and condoms, GoPuff has gone mainstream, and now offers 3,000 items ranging from over-the-counter medicine and laundry detergent to pet food and nail polish—all delivered in around 30 minutes for a flat $2 fee.
